Today's gas turbines demand maximum protection against environmental effects to ensure performance, longevity, and minimum maintenance. This machinery depends on high quality air to prevent fouling, erosion, and corrosion regardless of site conditions. Since gas turbines are installed in all types of environments from harsh deserts, to inner cities, to coastal regions, the air filtration system must be designed for specific environmental conditions. Properly conditioned inlet air is critical to keep gas turbines and other rotating machinery operating at peak performance.

Inlet Air Filtration

Inlet Air Cooling
Gas turbines ingest a constant volume of air regardless of the ambient air temperature. The density of the air entering the compressor affects the power output of the turbine. As the ambient temperature increases, the power output decreases. Typically, a 1° F temperature increase will result in a 0.5% decrease in power. In hot climates this reduction in power output can be significant and costly.

One of the simplest and most cost-effective ways to increase the output of a gas turbine is to increase air density. Cooling the inlet air recovers the power lost to high ambient air temperature and reduces heat rate. AAF provides a complete line of inlet air cooling systems including evaporation, fogging, and refrigerated chillers. The best inlet cooling system for a particular gas turbine will depend on its age, location, and operating cycle.
